[Pkg-utopia-maintainers] Bug#422752: network-manager: DHCPRELEASE sent *after* interface is disconnected.

[Jason Riedy]

Package: network-manager
Version: 0.6.4-8
Severity: normal


On a laptop with wired (eth0) and wireless (eth2) adapters, setting 
knetworkmanger to offline yields the following:

> May  7 21:04:28 nan NetworkManager: <information>^IGoing to sleep.
> May  7 21:04:28 nan dhclient: There is already a pid file /var/run/dhclient.eth2.pid with pid 5834

I don't think any of the broadcast concerns in 
/usr/share/doc/dhcp3-common/README.gz apply.  I suspect the wireless 
association is removed before dhclient runs, but I'm not sure how to 
trace the actual actions.  And I can't seem to get the dbus magic right 
to drop a script in /etc/network/if-down.d to release the lease and 
sleep a second.  If I could figure that bit out, I could at least test 
my assumption.

I'm set up to send a DHCP hostname to get a specific IP address.
Not sending the DHCPRELEASE means the server still thinks the wireless 
has the lease, and the wired adapter won't get the correct IP. 

Any help appreciated.  (The eth0 line in the above appears to be a 
separate problem.  There's always a dhclient3 running on eth0 even with 
no auto line in /etc/network/interfaces.  Blah.  I can't figure out 
what's running it.)
